In an isolated system, the total heat given off by warmer substances equals the total heat energy gained by cooler substances. Now look at your answer to Question 5. What might have caused the difference you have reported? Even though this data was provided to you, think of the errors the student could have encountered when collecting the data.

The temperature of the cooler substance was close to the room temperature. Therefore, the system experienced less change

Explanation:

Generally, in a closed system containing two bodies at different temperatures, there is a flow of heat energy from the body at a higher temperature to the body at a lower temperature. The effect is more significant when there is a large temperature difference between the bodies. However, if the temperature difference is small or insignificant, the change will be less.

small = small current large mag large current
